The brochure for the coaster says that, for the first 10 seconds of the ride, the height of the coaster can be determined by , h(t)=0.3t^3 - 5t^2 + 21t, where t is the time in seconds and h is the height in feet. Find the height of the coaster 9 seconds after the ride begins. Explain how you found the answer.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
